When in the Orlando area, two interesting (and large enough to see) land
shells to collect are Euglandina rosea and a Drymaeus sp. (cf. dormani?)
which can be found within the city limits.  Smaller, ubiquitous shells
but neat are the Polygyra septemvolva and larger P. auriculata.  Of
course the freshwater gastropods Pomacea and bivalves are more numerous
in many of the Karst topography lakes in the city.
